You have irony on many levels there. You say that your favorite computer is Windows? But Windows is not a computer, it's merely an Operating System that accounts for a reletavily high ammount of sales as of right now. I think your statement is quite inane and dull. Windows will never totally dominate, so it's a hyperbole anyways. And finally, if you used windows, I think you would be in for a pleasant surprise that Windows does indeed have a little tool called a Word Spell Checker.
